What level in the energy pyramid is a leopard seal?

Answer 1

Second to the top - they are predators but I believe that a Killer Whales probably kill and eat them so they are not the top predator.

So the pyramid would go (starting at the bottom):

Plankton -> fish-> penguin -> Leopard seal -> Killer Whale

Answer 2

A leopard seal would be categorized as a secondary or tertiary consumer in the energy pyramid, as it primarily feeds on fish, squid, and other smaller animals. This places the leopard seal at a higher trophic level due to its position as a predator in the food chain.
